Hey there! Today, we’re celebrating the birthday of a very famous scientist named Sir Isaac Newton. He was born in England almost 400 years ago and was super interested in how things move, even really big things like planets!
Sir Isaac Newton was not just a scientist; he was also a mathematician. A mathematician is someone who uses math to solve big questions about the world. Newton made many important discoveries, including figuring out that light is made up of different colors. He also helped invent a new type of math called calculus, which helps us understand how things change. Today, many people learn calculus in high school or college.
One of the most famous stories about Newton involves an apple. One day, he was sitting under an apple tree in his family’s garden when an apple fell from the tree. It might have even hit him on the head! This got Newton thinking about why things fall down instead of floating up. He came up with a big idea called the theory of gravity.
Gravity is a force, which means it’s like a push or a pull. It’s the reason why when you throw something in the air, it falls back down. Gravity pulls everything, like apples and people, toward the ground. It’s also why the moon goes around the Earth and why the Earth goes around the sun!
Newton discovered that really heavy things attract things that aren’t as heavy. This means that because the Earth is super big and heavy, it pulls things like apples and people toward it. That’s why we don’t float away! The Earth also pulls the moon, which is why the moon goes around the Earth instead of floating off into space.
The sun is even heavier than the Earth, so its gravitational pull is much stronger. That’s why the Earth goes around the sun. All of this is because of gravity, and Newton figured it out, possibly inspired by a falling apple!
The story about the apple is famous, but it might not be completely true. Newton himself used to tell it, but he never said the apple hit him on the head. Over time, people added that part to make the story more fun. However, we do know that Newton was inspired by watching apples fall from a tree.
To celebrate Newton’s birthday, maybe we should make an apple pie instead of a cake. Just don’t drop it to see if it falls—it would be much messier than dropping a regular apple!

Apple Drop Experiment: Find a small apple or any round fruit and a piece of paper. Hold them both at the same height and let them go at the same time. Watch what happens! Do they hit the ground at the same time? Try it with different objects. What do you notice? Talk about how gravity pulls everything down to the ground, just like it did with Newton’s apple.
Gravity Art: Create a piece of art that shows how gravity works. Use crayons or markers to draw a picture of the Earth, the moon, and the sun. Draw arrows to show how gravity pulls the moon toward the Earth and the Earth toward the sun. You can even add an apple falling from a tree! Share your artwork with a friend or family member and explain what you’ve learned about gravity.
Think About It: Imagine what life would be like without gravity. How would you eat, play, or sleep if you were floating around all the time? Write or draw your ideas. Discuss with your classmates or family how important gravity is in our daily lives and how it helps keep everything in place.
